Searching around a little more it seems that everyone was working on  
VR/IS. There are patents by other companies as well.

 From the Canon web site:

Canon started development of IS (Image Stabilizer) technology in  
1980s and introduced EF75-300mm f/4-5.6 IS USM in 1995, the world's  
first interchangeable lens for 35mm SLR with a built-in image  
stabilizer.

 From a Nikon model history web site:

The very well received and highly rated TW Zoom 150 QD of 1992 was  
selected to give a serious upgrade in 1994 as Nikon Zoom 700 VR -  
where I thought it should be called "105VR" to be more appropriate.  
However, the US version was more accurate to its spec. as it was  
referred as Zoom-Touch 105 VR). On a technical note, Nikon's VR  
(Vibration Reduction) technology was used to assist the new 38-105mm  
f/4~f/7.8 Nikon zoom to reduce chances of blurry images caused by  
unsteady hands during picture shootings.

I think the story that Nikon invented VR and sold the rights to Canon  
is probably apocryphal even though they were first to market. A year  
would not be enough even for Canon, I think, to develop a successful  
lens with an untried technology. Probably, as in other Japanese  
industries there was a lot of cross licensing and tacitly granted  
"sharing" from the time of the first research into it.
